Scientists at the Allen Institute have created the first detailed cellular atlas of brain aging.

They analyzed millions of individual cells and identified key regions where age-related changes first emerge.

Certain cell populations, particularly support cells called glia, were especially sensitive to aging.

As the brain ages, it shows increased immune activity across various cell types.

The identification of specific vulnerable cell types and regions gives scientists clear targets.
